METRA Commuter Rail
METRA commuter rail, and even Amtrak actually are about the easiest ways to get to Silver Cross Field. From the north-south waiting platforms the main entrance is nearly impossible to miss as it rises well above the track.
There are several convenient arrival/departure times the train is at the stadium/station. The "final departure," usually around 10:30 PM so locals "from the loop" (or just those staying downtown without a car) can make it safely "back home." If traveling alone, or catching other trains downtown you may want to leave on an earlier train since a 10:30 train won't arrive at the LaSalle Street in downtown Chicago until well after 11:00PM.
METRA Timetable Planning
Joliet is on TWO METRA routes: Rock Island and Heritage Corridor.
Like the song says, the "Rock Island Line is a very good line" and the most active. It runs east-west starting at the La Salle station with the end of the line in Joliet. It runs at least once an hour until 7:00 PM, then every other hour until 10:20.
The Heritage Corridor line runs only during "rush hour" so is not an ideal choice for attending a game. It ends at Union Station at both ends of the line (Chicago Union Station and Joliet Union Station).
Fares (2006):
Adult, One-way from Chicago LaSalle Street to Joliet Union Station: $5.15 (RI zone pair "AH").
Adult, One-way from Chicago Union to Joliet Union Station: $5.15 (Heritage Corridor; zone pair "AH").
METRA offers $5 "All you can ride" weekend passes and other deals for those without a car. Though more expensive than the $1.75 (one way any distance; $0.25 transfers) on the "L" (CTA), it stops right at the park (CTA's blue line ends at O'Hare and the taxi fare would add considerably more).
